Okay from Eternity’s thread:
Okay I timed out at ~30mins without a satisfactory answer. I thought this would be easier than it was.
I made some truth tables to help me out. The things I tried didn’t work. I was kind of just trying things out to see if I got any clues. But beyond guessing and checking I didn’t have any promising ideas on how to solve it.
This works but I’m not happy with it:
not(and(x,y))
